MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 453,207, dated June 2, 1891.

Application filed August 4, 1890.

To aZZ whom it mag concern.-

l 3e it known that I, JACOB H. PETERSON, a citizen of the United States, residing at Moreland, 1n the county of Webster and State of Iowa, have invented a new and useful Mechanical Movement, of which the following 1s a specification.

My invention relates to that class of mechanical movements especially designed for propelling vehicles; and it has for its object the provision of means by which an energy of comparatively small intensity at the point of application may be made to reappear as an energy of comparatively considerable i11- tensity at the point of application, in combination with means by which potential energy may be stored and utilized while the machine is at motion or at rest.

My invention consists, structurally, in a central drive-shaft within a suitable frame having double toothed perimeters, one of which meshes with the wheel mounted on a shaft, from which the movement of rotation may be communicated to the running-gear of the vehicle, and the other engaged by pawls secured to the pivoted linking connections of a hand-lever, so that the central drive-wheel may be rotated in one common direction in the reciprocation of the lever, in combination with pawls and ratchets and particular constructions and arrangements by which a spring coiled about the central shaft may be wound while the machine is at rest or in motion and its potential energy stored to assist in actuating the vehicle.

My invention consists, further, in pivoted pawls and ratchet-wheels which wind the spring fixed to the central drive-shaft during the operation of the machine.

My invention consists, further, in certain details of construction hereinafter more fully described, reference being had to the accompanying drawings, in which Figure 1 is a side view of my improved mechanism. Fig. 2 is a top plan view of the same. Figs. 3 and 4 are detail views illustratin g the separable lever, spring, and springwinding device. the central drive-wheel, one of the webs thereof being removed to show the spring. Fig. 6 is a sectional View of the central drive-wheel. Fig. 7 isa detail enlarged view showing the Fig. 5 is a side elevation of Serial No. 361,009. (No model.)

)arts 0 0 connected near their to ortions by means of a cross-piece c, Fig. 4.

The central drive-wheel B, as shown in Figs. 5, G, and 8, is made up of two webs e and 6', one of which 6 is formed with the toothed perimeters b b, and the one 6 adapted to be adjusted and bolted to the web 6 after the spring H is adjusted and secured in place, as

about to be described. Formed in two parts 6" and e is a central hub-wheel E, keyed to the collar h, which said parts are bolted together, one end of the convolute spring H being first secured to the pin 71. Both of the webs c and 6 being perforated at their centers, the Web e is first slipped over and upon the shaft B and adjusted in position upon the flanges of the central hub E as shown more clearly in Fig. 8. The spring 11 is then disposed within the interior periphery of the perimeters b and b, as shown in Fig. 5, its remaining outer end being secured to the pin h", after which the remaining web 9 is'adjusted in place and bolted to web 6, thus forming the completed wheel B, with the spring disposed within its interior, the said wheel B being mounted upon the shaft B fixed in the frame and free to rotate independently about the same and independently also of the collar h, except that in the case of the latter the central hub E", being keyed to the collar h, mounted on the shaft 13 is connected by the spring ll to or near the periphery of the wheel 13, said wheel, however, revolvin g entirely independently of the stationary shaft B Referring to Fig. 7, the means of winding the spring is more clearly shown, in this instance but one ratchet-wheel J 2 being employed, secured to the collar 71, which is the preferred form.

D is a horizontal connecting-link pivotally connected to the lower end portions of the connecting-pieces D at one end and at the other pivotally connected to the vertical connecting-piece D", the upper end of which latter is pivotally connected to the ends of horizon talconnecting-pieces D, the other ends of which latter are pivotally mounted about the axis B of the central drive-wheel B. Between the connecting-pieces D is pivoted a pawl D held in engagement with the perimeter Z of wheel B by means of spring (1.

Dis an arm pivoted at one end to the point of junction between the horizontal connecting-link D and the vertical connecting-link D and at its other end pivoted within the end of the frame A.

The perimeter l) of the central drive-wheel B is formed with teeth, which mesh with those of a pinion E, mounted fixedly on the shaft E, which latter finds its bearings within the frame A. The pinion E is fixed to a sprocket-wheel E also fixedly mounted on the shaft E It is evident, however, that the wheel EEbeing the last in the train of mechanism, may be of a character suitable for the performance of the given work.

II is a convolute spring, which is disposed about and has one of its ends secured to a collar or sleeve 71, loosely mounted in the frame and adapted to be rotated in manner to be described. Through the central drivewheel shaft 13 passes the other end of the spring, being secured to the wheel B by means of a pin, (not shown,) the spring Hin turn being secured to the pin, the lever C being made up of two parts, one of which 0' is adapted to be separated from the other e by a latch 0 holding said part c to the crosspiece 0'. The separable part c has secured to its lower end check-plates J, which are mounted on collar h and hold pivoted between them a spring-pawl j, which engages the teeth of the ratchet-wheel J fixed to said collar h. j is a spring-dog, also engaging the teeth of the ratchet J J is a ratchet-wheel, also fixed to the collar 71, engaged by the spring-'pawlj", which latter is pivoted on the connecting-piece D The operation of my device is as follows: The operator actuates the lever 0 through the medium of the connecting-pieces D, the horizontal connecting-link D vertical connecting-link .D, and horizontal connectingpieces I), the pawl D engaging the perimeter b of and rotating the central drive-wheel in the one movement of the lever G, and the pawl D engaging the perimeter Z) of and retating the said wheel in the same direction on the movement of the said lever in the opposite direction. By this means a practically continuous rotation of the central drivewheel I is obtained, which is transmitted to the sprocket-wheel E In the actuation of the lever C the pawl 7, pivoted between the check-plates J, engages the ratchet-wheel J fixed to the collar h, which latter in turn rotates the central hub E", winding the spring II, this being accomplished in the backward movement of the lever 0, which lever in its forward movement causes the pawl J" to engage and actuateits ratchet-wheel J the dog 7" serving to keep the spring II from unwindin I If it be desired to wind the spring ll when the machine is at rest, the operator may operate the lever C by unlatching and disconnecting the part c, and said part through the medium of its pawl J, acting on ratchet-wheel J may then be employed to wind the spring.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-

1. The combination, in a mechanical movement, of a central drive-wheel, a spring arranged about a sleeve, the latter having a ratchet or plurality of ratchet-Wheels fixed thereto, said spring being secured to the cen tral drive-wheel to actuate the same, and pawls engaging the ratchet-wheels, said pawls being actuated to wield the spring in both movements of the actuating-lever, as and for the purposes set forth.

2. In a mechanical movement, a separable actuating-lever formed of two parts, a central drive-wheel, a plurality of pawls engaging the drive-wheel, connecting-links carrying said pawls actuated by one of the parts of said levers, a spring secured at one end to the central drive-wheel, a sleeve to which the other end of the spring is fixed, a ratchetwheel carried by said sleeve, and a pawl or pawls engaging said ratchet-wheel, actuated by the other part of the lever to wind the spring when the machine is either in motion or at rest, as set forth.

3. In a mechanical movement, a central drive-wheel having double toothed perimeters, a plu 'ality of connecting-links operated by a lever, a plurality of pawls engaging the perimeters of the central drive-wheels, operated by the lever, a convolute spring disposed within the central drive-Wheel and having one of its ends fastened thereto, a rotatable sleeve mounted upon a stationary axis secured in the frame to which the remaining end of the spring is fixed, a ratchet wheel or wheels fixed upon said sleeve, and a pawl or pawls actuated by the lever, engaging said ratchet wheel or wheels, as set forth.
